HANS MIKOREY, OF SCHGNEBERG, NEAR BERLIN, GERMANY, ASSIGNOR TO THE FIRM OF MINIMAX CONSOLIDATED LIMITED, OF BERLIN, GERMANY.

SPRAYER FOR GLUE-PAINT, LIQUID GLUE, AND THE LIKE.

To all whom it may concern:

Be it known that I, HANs Muronnv, a civil engineer, and a subject of the German Emperor, and a resident of 13 Wartburgstrasse, in the city of Schoneberg, near Berlin, Kingdom of Prussia, and German Empire, have invented a certain new and useful Sprayer or Disperser for Glue-Paint, Liquid Glue, and the Like, of which the following is a specification.

This invention has reference to a sprayer or dis erser for glue paint, liquid glue, and the 11 re, which is so arranged and constructed, that it can be easily inserted into a water bath and removed therefrom, in order to be able to heat its contents or to maintain the temperature thereof.

On the drawings three forms of execution of the subject matter of the invention are shown.

Figure 1 shows the sprayer in section, inserted into the heatin device. Fig. 2 is a plan view of Fig. 1. *ig. 3 is an elevation and part section of another form of construction of the disperser or sprayer with means for the pre-heating of the pressure fluid. Figs. 4 and 5 are respectively plan and side views of the sprayer or disperser according to Fig. 3; ig. 6 is another form of construction of the sprayer or disperser with means for heating the same durlng the operation.

The container a for the reception of the liquid glue, the glue paint or the like, is provided with a nozzle 0, possessing a valve 5, and below which the com ressed airdelivering nozzle d is arrange The air admission pipe 6 is preferabl arranged, so as to he arallel to the container a, and at a suitable eight it is bent sidewise, so as to serve as a support for the sprayer together with the stops f and g or the like which are situated at a level with this bent portion; the said sprayer being kept suspended in the heating vessel h which may be filled with water. Upon the air conducting pipe e the handle 2' is mounted at the outslde of the heating vessel h, so that the sprayer or diserser can be conveniently inserted into the heatin vessel and removed therefrom. Inasmuc as in this arrangement of parts the nozzles are also inserted into the heating Specification of Letters Patent.

vessel, obstruction and choking up of the same by dry glue or the like is obviated.

The heating vessel It is referabl supported on feet 76 and may he heate by a burner m, fed with liqui or gaseous fuel. The arrangement and mode of operation of the valves of the sprayer or disperser may be whatever desired.

In the second form of construction of the sprayer or disperser (Figs. 3 to 5), the heating vessel It for the reception of the container a for the liquid glue or the like, is surrounded by a jacket r in which a coil 11 or the like, surrounding the container, is arranged, so as to cause the heating by means of the excess heat rising up from the heating device m. The heating coil it constitutes a part of the conduit for the compressed air, serving for the operation of the sprayer or disperser, the said coil effecting the preheat ing of the air, so that, when working with the sprayer or disperser, the nozzles are kept hot, in order to prevent, as much as possible, any solidification of the glue, of the glue paint or the like, so as to prevent any choking up of the nozzles. The compressed air, required for the operation of the sprayer or disperser, is admitted into the coil 1 by means of the pipe 6, and it then passes off in a heated condition through the pipe p.

The heating of the coil 7?. takes place partly from the container h, and partly from the heating gases, ascending from the burner m and along the outside of the container it. These gases heat the compressed air, passing through the coil n, according to the counter-current principle. The jacket 7 which surrounds the coil n at a certain distance, and which is preferably downwardly enlarged for the purpose of being sure to catch the ascending gases, presenting a bellshaped appearance, acts to insure the flowing of the excess of the ascendin heating gases of the heatin device m to t e coil n. This jacket r is pre erabl so arranged, that its upper rim is not closely connected to the container h, in order to insure the passing of the heating gases through the jacket. For the same purpose openings 8 ma be arranged likewise m the upper part 0 the jacket.

It is of advantage, to connect the jacket 1' with the coil it into a. unit, and to rovide the {acket 7 with spring acting llO0(S t or the ike, engaging with the upper edge of the container it and thereby securing the jacket and the coil from becoming detached and falling down from the container It. By means of this arrangement it is possible, to detach the coil u and the jacket 1" easily from the container it for cleaning and repairing )urposes. The pipe 1) is preferably arrange with a fork-shaped end u to which two nipples o and 10 for the attachment of a hose or rubber tubing, are secured. From these ni ples flexible metal tubings or the like, lead to the nipples w of two dispersers or sprayers, so that it is possible to work with one disperser or sprayer, While the other sprayer is kept suspended in the heatin vessel.

Tn order to prevent the contents of the sprayer or disperser from cooling down comparatively quickly, after the sprayer has been removed from the heating device, and after it is operated, the container a of the disperser or sprayer may be heated by hot air or by any other means during operation, so that the contents of the spraying receptacle can be cooled oil only at a slow rate. Fig. 6 illustrates a form of construction of this kind of sprayer or disperser which can be heated during the operation, and which may be connected for instance to the dis charge end u of the coil 91, in accordance with Figs. 3 to 5. The liquid container a of the sprayer or disperser according to Fig. 6 is surrounded at a certain distance by a jacket 1. In the space between the container a and the jacket 1 a coil 2 is arranged which is connected on the one hand to the air conducting pipe e, and on the other hand to the air nozzle d of the disperser or spray er by means of the pipe 3. The jacket 1 surrounds the container a, making a close fit, so that loss of heat is avoided as much as possible. The air, Which has been heated in any suitable manner, is admitted into the coil 2 by means of the nipple m, the air filter 4 or the like, and the pipe 6, the air com munieating part of its heat to the liquid container 0., and escaping through the pipe 3 and the nozzle cl sufliciently hot yet, for preventing solidification of the liquid upon or in the interior of the nozzles. The device may also be utilized, if desired, for using the heat, discharged from the container a, as a means of heating the air, introduced through the nipple w, by the action of the coil 2, so as to prevent solidification of the liquid in the interior and at the nozzles. As will be seen from Fig. 6, the handle 1' in this form of construction of the sprayer or disperser is not parallel to the longitudinal axis of the liquid container a, but the handle is bent,

at an angle of 45 degrees for instance, in order to prevent heating of the handle by the source of heat. By means of the ar rangement of handle described, the manipulation of the sprayer or disperser is also facilitated, inasmuch as the handle can be touched more conveniently.

What I claim and desire to secure by Let tors Patent of the United States is r l. The combination, in a disperser or sprayer for glue paint, liquid glue, and the like, of a liquid container carrying a nozzle, an air ctiinducting pipe, provided with a nozzle and ooniiectcd to and carried along this container, and a heating vessel, capable of being heated, in which the said liquid container, inclusive of the liquid nozzle and the air nozzle may be inserted, all substantially as set forth.
